Three conceptual pillars of Ecosystem-based Adaptation

Ecosystem-based adaptation (EbA) is an approach to climate change adaptation that harnesses biodiversity and ecosystem services to reduce the vulnerability of human communities to the adverse effects of climate change. This strategy involves the sustainable management, conservation, and restoration of ecosystems to provide services that help people adapt to the impacts of climate change.

Principles

Ecosystem-based adaptation is grounded in several key principles:

• Sustainability: Ensuring that the use of natural resources does not compromise the ability of ecosystems to provide services in the long term.
• Biodiversity Conservation: Protecting and enhancing biodiversity to maintain ecosystem resilience.
• Community Involvement: Engaging local communities in the planning and implementation of adaptation strategies.
• Adaptive Management: Continuously monitoring and adjusting strategies based on new information and changing conditions.

Benefits

EbA offers multiple benefits, including:

• Enhanced Resilience: Healthy ecosystems can buffer against extreme weather events, such as floods and droughts.
• Cost-Effectiveness: EbA can be more cost-effective than engineered solutions, such as seawalls or dams.
• Co-Benefits: In addition to climate adaptation, EbA can provide other benefits, such as improved water quality, increased biodiversity, and enhanced livelihoods for local communities.

Examples

Examples of ecosystem-based adaptation include:

• Mangrove Restoration: Restoring mangrove forests to protect coastal areas from storm surges and erosion.
• Agroforestry: Integrating trees into agricultural landscapes to improve soil health, increase water retention, and provide shade.
• Wetland Conservation: Preserving and restoring wetlands to enhance water storage capacity and reduce flood risks.

Challenges

Despite its benefits, EbA faces several challenges:

• Funding: Securing adequate funding for large-scale implementation.
• Policy Integration: Integrating EbA into national and local policies and planning processes.
• Knowledge Gaps: Addressing gaps in scientific knowledge and data on ecosystem services and their role in adaptation.
